Intravaginal (IVAG) inoculation of wild-type herpes simplex virus
type 2 (HSV-2) in mice causes epithelial infection followed by lethal
neurological illness, while IVAG inoculation of attenuated HSV-2 causes
epithelial infection followed by development of protective immunity
against subsequent IVAG challenge with wild-type virus. The role of T
cells in this immunity was studied by in vivo depletion of these cells
with monoclonal antibodies. Three groups of mice were used for each
experiment: nonimmune/challenged mice, immune/challenged mice, and
immune depleted mice [immune mice depleted of a T-cell subset(s)
shortly before challenge with HSV-2]. Mice were assessed for
epithelial infection 24 h after challenge, virus protein in the
vaginal lumen 3 days after challenge, and neurological illness 8 to 14 days after challenge. Monoclonal antibodies to CD4, CD8, or Thy-1
markedly reduced T cells in blood, spleen, and vagina, but major
histocompatibility complex class II antigens were still partially
upregulated in the vaginal epithelium after virus challenge, indicating
that virus-specific memory T-cell function was not entirely eliminated
from the vagina. Nevertheless, immune mice depleted of CD4+
and CD8+ T cells, Thy-1+ T cells, or
CD8+ T cells alone had greater viral infection in the
vaginal epithelium than nondepleted immune mice, indicating that T
cells contribute to immunity against vaginal HSV-2 infection. All
immune depleted mice retained substantial immunity to epithelial
infection and were immune to neurological illness, suggesting that
other immune mechanisms such as virus-specific antibody may also
contribute to immunity.
